NR-24298??Borrelia burgdorferi, Signature-Tagged Mutagenesis Library Clone T07TC272 (Gene BBK26)(Mutant Bacteria)|Borrelia burgdorferi|Signature-Tagged Mutagenesis Library Clone T07TC272 (Gene BBK26)|-80°C or colder|SJ NorrisAcknowledgment for publications should read "The following reagent was obtained through BEI Resources, NIAID, NIH: Borrelia burgdorferi, Signature-Tagged Mutagenesis Library Clone T07TC272 (Gene BBK26), NR-24298."|Quantity limit per order for this item is 1. This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.
Borrelia burgdorferi (B. burgdorferi), clone T07TC272 was produced by signature-tagged mutagenesis (STM) of the BBK26 gene.
B. burgdorferi, strain B31, clone 5A18NP1 was derived from the low-passage clone 5A18 of strain B31. Clone 5A18NP1 lacks Ip56 and Ip28-4 and the BBE02 gene (a putative restriction-modification gene on Ip25) was disrupted by homologous recombination resulting in kanamycin resistance. Inactivation of BBE02 results in increased transformation efficiency and therefore, clone 5A18NP1, was used to create the STM library through the mariner-based transposition suicide Himar1 delivery vector, pMarGent, containing aacC1 which confers gentamicin resistance. STM is a negative selection method that identifies clones by unique DNA sequences that are incorporated into the transposable element.
B. burgdorferi, strain B31 5A18NP1 STM library clone T07TC272 lacks linear plasmids lp28-4 and lp56. The plasmid profile was determined by PCR using plasmid specific primers.
The complete genome of B. burgdorferi, strain B31 has been sequenced (GenBank: AE000783).
Each vial contains approximately 0.5 mL of bacterial culture in Revised Barbour-Stoenner-Kelly medium supplemented with 200 ?g/mL kanamycin, 40 ?g/mL gentamicin and 15% glycerol.
Additional information and tools are available at PATRIC (Pathosystems Resource Integration Center).

厂牌介绍
BEI Resources 由美国国家过敏和传染病研究所 ( NIAID )成立,旨在为研究 A、B 和 C 类优先病原体、新兴传染病病原体、非病原微生物和其他相关微生物材料提供试剂、工具和信息到研究界。BEI Resources 获取、验证和生产科学家进行基础研究和开发改进的诊断测试、疫苗和疗法所需的试剂。通过将这些功能集中在 BEI Resources 中,可以监控科学界对这些材料的访问和使用,并确保试剂的质量控制。
除了为传染病界提供材料外,BEI Resources 还鼓励和支持研究人员和机构的材料存放。使用 BEI Resources存放材料对研究人员和研究社区有许多优势,包括安全存储、社区访问和分发;同时保护存款人的知识产权。只要有需要,BEI 资源库将作为研究人员的资源进行维护。您在 BEI Resources 的存款是一项有助于未来研究的长期投资。
BEI Resources 自 2003 年起由美国典型培养物保藏中心 (ATCC) 根据合同管理。2016 年 5 月, ATCC获得了一份为期七年的继续管理 BEI Resources的合同。合同范围已扩大到更全面的研究目录材料,包括由其他政府支持的研究项目存放的材料,将提供给生物防御和新兴传染病科学界。真菌、寄生虫、载体和其他相关材料已添加到现有的细菌、病毒和毒素试剂中,涵盖 NIAID A、B 和 C 类优先病原体和 NIAID 指定的新发传染病病原体和生物。
